THE PERSONAL VALET CLOTHES
VITALIZING SYSTEM
The Personal Valet Clothes Vitalizing System
is designed to freshen any previously worn
clothing so that it is "ready to wear." It works
for both dry cleaned and non-dry cleaned cloth-
ing. One of the key components of the system
is the special solution, called Presiva
tures odors, and removes wrinkles from the
fabric. The solution is manufactured by Procter
™
and Gamble for use in the clothes vitalizing
system.
Presiva is made up of donut-shaped molecules
that capture odor particles in the clothing,
"surfactants" to spread the Presiva droplets
over the fabric, and perfumes that freshen hard
to handle odors.
Presiva comes in two varieties:
1. A Soft formula that contains silicone to
lubricate the fabric and smooth wrinkles,
leaving a soft feel to the fabric. It is in-
tended for all types of fabric.
2. A Crisp formula that adds a polymer to
lock fibers in place, leaving a starch-
like finish to the fabric. It is only in-
tended for use with cotton clothing.
HOW IT WORKS
The clothes vitalizing system uses a compres-
sor to force air over a nozzle that is located at
the top of the Presiva container. The forced air
"atomizes" the solution, which forms a "mist"
that is distributed over the clothing inside the
cabinet.

The domed shape of the cabinet's interior helps
to distribute the mist over the surface of the
clothing in the most effective pattern for uni-
form fabric deposition. An interior air port near
the bottom of the cabinet creates an opposing
air flow to further enhance the mist dispersion.
The air flow creates a "figure eight" pattern.
